2 Claims.

This invention relatesto new and useful improvements in type setting machines and more particularly to the usual rotating cam operating rolls, as depicted in Patent No. 787,821, issued April 18, 1905.

The principal object of the present invention showing the racks containing the rolls and the heating means therefor.

Figure 2 is a longitudinal sectional view taken substantially on the line 2-2 of Figure 1.

Figure 3 is a transverse sectional view taken substantially on the line 3-3 of Figure 2.

Figure 4 is a perspective view of one of the wooden rolls showing the reduced ends and the metal sleeves thereon.

Figure 5 is a plan view of the friction spring.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to a conventional portion of a type setting machine, this including racks 6, 1 for the reception of rolls 8, 9, respectively. These rolls are at present constructed of metal, but in carrying out-the present invention it is intended that the same be wood, one end being reduced as at W and the other end being reduced as at H, but a somewhat longer reduction than the reduction 10. On the reduced portions of the rolls 8 and 9 are metal sleeves l2,

l8, respectively, and these are preferably forced into retained place on the reduced portions and are disposed through bearings M on the racks when properly mounted.

The elongated reduced end I I projects well beyond its corresponding bearings 14 and these projecting portions of the rolls are equipped with gears l5, IS, the rear roll 8 preferably having a pulley on its reduced portion to accommodate a drive belt IT. The gears I5, l6 mesh and are held in retained position for driving the rolls by springs I8, these springs are of cross-shape, each leg being curved as at l9 to bear against the adjacent gear H3 or IS. The center of the spring l8 has an opening 20 through which a machine screw or the like 2| is disposed and threadedly disposed into the corresponding end of the reduced portion l l. The leg portions of the spring 18 press the corresponding gears l5 or l6 snugly against the adjacent ends of the corresponding sleeve IS.

The springs l8 serve as frictional clutches for the gears allowing the gears to rotate even though the rolls have become locked.

Inasmuch as the rolls 8, 9 are to be of wood, moisture or other conditions may serve to modify action on the usual cam means. A heat box 22 is provided and located just below the space between the rolls, it being preferable that the box have beveled upper portions 23 in opposed relation to the rolls 8, 9. A conduit 24 extends from a suitable heat source to the box 22.

Thus it can be seen, that heat is constantly supplied to the rolls and rises up through the rack assembly 5 to reach associated mechanism for the purpose of always keeping the mechanism warm and the lubrication heated so that there will be no likelihood of stoppage due to bindings as result of hard lubrication or similar faults.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. In a type setting machine, cam actuating rolls, said rolls being of wood, and a heat box located under said rolls for maintaining the rolls substantially dehydrated at all times.

2. In a type setting machine, cam actuating rolls, said rolls being of wood, a rack for the rolls, and a source of heat located under the rack and in close proximity to the rolls for maintaining the rolls substantially dehydrated at all times.
